Application filed September 25, 1902. Serial No. 124,792. (No model.)

To all whom, it may concern.-

Beit known that I, ELWIN STRICKLAND, a citizen of the United States, residing at Los Angeles, county of Los Angeles, State of California, have invented certain new and useful Improvements in Union Cable and Drill- Tool Sockets; and I hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which- Figure l is a longitudinal central section of a combined or union cable and a drill-tool socket embodying my invention, the parts being in the position they occupy at the instant the cable is freed of its load. Fig. 2 is a detached view of the upperor adjustable ratchetplug of the outer member of the socket. Fig. 3 is a View of the lower or ratchet end of the part shown in Fig. 2. Fig. 4 is a detached view of the lower or fixed ratchet-plug of the outer member of the socket. Fig. 5 is a View of The upper or ratchet end of the part shown in Fig. 4. Fig. 6 is a detached view of the ineluded or escapement member of the socket, which also performs the function of the cablesocket. Figs. 7 and 8 are respectively top and bottom or opposite end views of the parts shown in Fig. 6, showing the ratchet-faces thereof; and Fig. 9 is a detached view of a short section of brass or similar tubing, which extends up from the cable-socket or escapement member and which serves to shield the cable from wear where it passes through 'the upper annular ratchet-plug of the outer member or tool-socket.

Like symbols refer to like parts wherever they occur.

My invention relates to that class of devices intended to be interposed between and form the union of a drill-cable and drill-tools for utilizing the rotary movement incident to the unlayin g of the cable-strands when loaded and their relaying when relieved of the load for the purpose of changing the position of the drill with relation to the cable on successive strokes of the drill, whereby the perfectly round character of the hole being drilled is preserved and the drill-tool prevented from sticking or wedging.

The common practice in drilling Artesian and like Wells is to so manipulate the drilldent to the usual swivel-and-clutch combinations employed for such purposes and to effeet a limited and regulated step-by-step rotation of the drill, so that the operation of said drill shall be uniform and exact, is the object of my present invention, and this I accomplish by the iianterposition of an escapement device or mechanism between the drillcable and drill-tools,'and lsuch a combination of cable, drill-tool, and interposed escapement device embodies the main feature of my invention.

In carrying out my invention I preferably so combine a cable-socket and a drill-tool socket, the former being the included member and being provided at its opposite ends with ratchet-teeth and the latter being the including member and provided at its opposite heads with corresponding ratchet-teeth, the ratchet-teeth on both members being inclined in the same direction, and said members having a relative radial and longitudi-l nal movement, that the cable-socket shall constitute the escapement and the drillsocket. the pallet member of the escapementv combination, and -snch a construction embodies a second feature of my invention.

There areothery minor features of invention, all as will hereinafter more fully appear.

I will now proceed to describe my invention more fiilly, so that others skilled in the 'art to which it appertains may apply the same.

In the drawings, A indicates the outer or including member of the socket and which may be termed the drill-tool socket, and B the inner or included member of the socket and which constitutes the cable-socket as f well as the escapement member of the combination, the two parts when combined constituting a union socket for the cable and the drill-tools.

The outer member A, which is 0f tubular form, is provided at its upper end with a slight shoulder 1, which somewhat reduces the bore above the' same, where it is threaded, as `at 2, for the reception of a threaded annular plug C, and said member A is also threaded at its lower end, as at 3, to form a box for the reception of the pin ot a sinkerbar jar or drill-stem, as the case may be.

C indicates an annular plug having on its lower end ratchet-teeth c and threaded above, as at 2Q, where it engages the threaded interior or bore of the outer member A, so that said plug may be adjusted in the bore of the member A to compensate for wear of the ratchet-teeth of the escapement devices. The upper end of ratchet-plug C is provided with wrench-seats 4 and a jam-nut 5 or equivalent means, whereby the ratchet-plug may be fixed after adjustment.

D indicates a second annular plug having ratchet-teeth d on its upper end, and said plug D is secured in the lower end of the bore ofthe member A just above the box 3 by a dowel-pin 6 or in othersutable manner. The

,. distance between the upper ratchet-teeth c and the lower ratchet-teeth d of the member A is slightly greater than the length of the included or escapement member B, with the teeth of which said teeth c and d correspond and engage alternately, as will hereinafter ap'- pear.

a a, indicate vents or passages for the escape of any liquid which might otherwise impede the movement ofthe member B.

B indicates the included or escapement member of the device, and in this instance, as it is also the cable-socket, its interior is tapered below to permit of securing the cable therein and is threaded above, as at 7, to receive the lower threaded end of a short tube E, of brass or other suitable metal, through which the cable passes. This cable-socket and escapement member has at its opposite ends ratchet-teeth b b', which correspond with and alternately engage the fixed ratchet-teeth c and d above and below on the upper and lowerratchet-plugs C and D ofthe member A.

E indicates a short tube of brass or other suitable metal threaded at one end, as at 8, to engage the thread 7 in the upper end of the bore of the cable-socket and escapement member B. The inner diameter of the tube E is such as to permit the passage of the drillcable, which it incloses and shields against wear incident to the reciprocation and rotation of the. cable, and its outer diameter is such as to permit it to reciprocate and rotate freely in the axial opening of the upper annular ratchet-plug C, through which it passes.

The ratchet-teeth b and b of the inner or escapement member B and those c d of the outer member A correspond in form, as herelinbefore pointed out, and are made up of inclined and vertical sides, the number of teeth andl length of their inclined faces (or Width of base of tooth) being determined by the extent ot rotation of the tool desired at each successive stroke,(in the present instance the teeth are shown as four in number,) and the inclination of the teeth will depend on the laying of the cable-strands. The included Vmem ber B when released from load may be `clamping it in position bythe jam-nut 5, next screwing the threaded end of tube E into the threaded upper end of the bore of the member B, and passing the parts E B into the bore of the member A from ,below until the V upper end of tube E projects slightly from the annular'plug C and the ratchet-teeth Z) engage the 'ratchet-teeth c, after which the lower or fixed annular ratchet-plug D may be inserted and secured by the dowel-pin 6.

OE course when the device is to be secured vto the cable the end of the cable will be passed through the annular plug C of the member A, drawn out at the lower end 0f said member A, and passed through tube E into the socket and escapement member B, where it will be secured in the usual manner, after which the cable will be drawn back, so as to carry the tube E into the annular ratchetplug C and the part B within the bore of member A, after which the xed ratchet-,plug D will be inserted and secured by the dowelpin 6, as before specified.

The operation of the union cable and drilltool socket or escapement-socket will be as follows: When the load is on the cable, the ratchet-teeth b c will be in engagement and the parts or members A BV will be locked and rotate together by reason of the elongating or unlaying of the strands; but at the instant the Weight is released from the cable the part B will irst rewind in the member A, which will cause the teeth b d to engage, (see Fig. 1,) at which time the cable, being relieved of its load, will remain in that position until it receives the weight of the tools and until the longitudinal upward movement of the part B is eected, so that the upper tooth b skips or escapes the first or adjacent tooth c, and as this lift of the cable takes place and the weight. of the drill-tools or load is again assumed the drill-socket member A and attached drill-tool make a partial (quarter) rotation equal to the width of the ratchet-tooth at its base.

IIO

The foregoing operation of the devices is repeated with each lift and drop of the tools, the teeth b b' of the escapement member B coacting with the teeth c d or pallets of the member A to limit and regulate the relaying of the cable and the extent of rotation of the drill-tool'. y

Having thus described my invention, what I claim, and desire to secure by Letters vPatent, is-

1. A combined cable and drill-tool socket provided with escapement devices actuated solely by the unlaying and relaying of the drill-cable, substantially as and for the purposes specified.
